ALBERT E. BROWN, OF POOLVILLE, NEW YORK.

THILL-GOUPLING.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed December 18, 1912. Serial No. 737,442.

To all whom it may concern:

Be it known that I, ALBERT E. BROWN, a citizen of the United States, of Poolville, in the county of Madison, in the State of New York, have invented new and useful Improvements in Thin-Couplings, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to certain improvements in thill couplings comprising a fixed jaw, a movable jaw, a coupling pin and a suitable packing interposed between the coupling pin and jaws.

The main object is to provide a leather or fibrous packing with a metal reinforcement, such as woven wire incorporated therein, so as to establish a firm grip therewith and to utilize portions of the reinforcement as a fastening means for attaching the packings to the jaws so that the packings may be permanently shaped to fit the jaws and coupling pin with less pressure than that required for forming all-leather packings.

Other objects and uses will be brought out in the following description.

In the drawingsFigure 1 is a side elevation, partly in section, of one form of thill coupling embodying my improved packing. Fig. 2 is a. sectional View of a portion of another form of coupling and packing with the reinforcement adapted thereto.

The thill coupling shown in Fig. 1 comprises a fixed aw 1, a movable jaw 2 and a coupling pin 3 having a spherical central portion 4, the coupling pin forming an integral part of a thill iron The fixed jaw 1 forms an integral part of a clip 6- which is adapted to be secured in any well known manner to an axle not shown, said fixed jaw 1 havin a s)hcrical socket 7- oaenin from' its under side and of sufiicient diameter to easily fit over and upon the coupling pin 8 and its spherical portion 4. A composition packing section is seated in and conforms to the contour of the spherical socket T and has its lower front and rear edges projecting downwardly at the front and rear of the adjacent portion of the jaw 2 and spaced a suflicient distance apart to receive the latter jaw, which is movable in the lower open side of the socket 7 and against the under side of the coupling pin 3- and spherical section 4-, and is provided with a composition packing section 21. The packing section in the fixed jaw 1 is composed of a main body 18 of leather or fiber and a metal reinforcement 19, preferably of woven wire embedded or incorporated in the main body 1S substantially coextensive therewith, portions thereof being looped outwardly through apertures 20 in the jaw for retaining the packing in fixed relation to said jaw against accidental displacement. The packing in the lower movable jaw 2 is also composite, being made up of a body -21'of suitable material and a wire fabric bond 22 having portions thereof extended through apertures 23 in the lower side of the jaw 2 and clenched upon the outer face thereof to retain the packing section 2l in place.

In Fig. 2 I have shown a fixed jaw 25 and a movable jaw 26 as embracing a cylindrical coupling pin 27, the jaw -26 being hinged at its front end at Q8 to the fixed jaw 25-. In Fig. 2 the jaws 25 and -26 are each provided with a semicylindrical composite packing section composed of a leather or fibrous body 87- and a wire fabric bond 3S portions of the latter being passed through apertures -39 in their respective jaws for retaining the packing in place.

It will be observed in each of these several modifications'that each jaw is provided with a separate packing section secured thereto by a portion of the wire fabric which extends through the apertures of the jaws and constitutes retaining staples for the respective packings.

The packing sections shown in Figs. 1 and 2 may be made of felt or other absorbent material capable of retaining a lubricant, such as graphite or oil, to reduce the wear of the packing, the wire reinforcements serving to retain the shape of the packing when once formed in the jaws and upon the coupling pin, while the portions thereof which are clenched to the jaws serve to hold the packings against accidental displacement, the reinforcements also serving to prevent wrinkling or crumpling of the fibrous material as the coupled parts move one upon the other, all of which tends to increase the life and efficiency of the packing.

What I claim is 1. A packing for thill couplings comprising a fibrous body and a metal reinforcement incorporated therein.

In Witness whereof I have hereunto set my hand this ninth day of December, 1912.

ALBERT E. BROWN.

2. A packing for thill couplings comprising a fibrous body and a, Woven Wire reinforcement incorporated therein.

3. A packing for thill couplings comprising a fibrous body and a Woven Wire reinforcement incorporated therein, and having a portion thereof attached to the coupling.
